My invention relates to check'detectors and more particularly toy 'adevice of this character that is adaptedforuse in ascertaining whetherornot a check has been'raised f5 when presented to'a'ba'nk for payment.Certain objects of the invention are to provide a detector device with aslidable perforated and numbered element that may be shifted tonumerouspositions in cooperative rel ation with a scale whereby theposition of a check placed thereon and inregistry with certain otherscales, in conformity with' a predetermined combination or key numbercomprising readings on said scales, will fixthe posi# tion individuallyfor the bank depositors and whereby holes-may be punched through thecheck by the depositorito correspond with the amount for which the checkis drawn,

and whereby any raising of the cheek may be detected by placing thecheck within a duplicate device by the cashier ofthe bank when same isVpresented for payment. Other objects are to providev adjustable meansfor the slidable element, to provide a slidabl y ad.'

justable guide member for the check, and to provide other novel detallsof construction land arrangement as hereinafter set forth.

With the above and yother objects in which will appear as thedescription view proceeds, the invention consists of thenovelconstruction, adaptation, combination and ar-- rangement of partshereinafter ydescribed `and claimed. These objects are accomplished' bydevices illustrated in drawings; wherein :f

As shown inv Fig.

8, the sides of said recess and beveled if desired. l

The means for adj ustably moving kthe block member 8 back and forthwithin its recess 7 comp-rises a ba-r 9 that is slidably disposed andbeveled into a recess extending rearwardly through the portion of thetop 5 from the recess 7. Said bar may have a bracket arm 10 with a screw11 threadedly disposed therethrough and swiveled throughl a bracket lug12 that is secured to* said top. A slotted arm 13may be adjustablysecuredto said bar byaclainp screw14 and said arm is block may bev asdesignated provided with a pin 15 at its inner end that is arranged tofit into a hole in the slidable block member. Thus by turning the screw11 said'block member may be moved back orforth and byloosening'said'clamp screw the slotted armv maybe raised, as shown inAlong the upper margin of said system of rectangles each verticalYcolumn thereof is numbered from one to ten beginning at the left, andalong the left hand edge the horizontal columns are lettered from A to Jbeginning at the bottom. In each of said small rectangles a number isplaced above and a letter is placed below its perforation. Although notarranged consecutively or alphabeticallysaid numbers range from zero toten in each vertical and horizontal column of rectangles and saidletters range from A to J in said columns. c A sc r-ew'member-l having apointer directed toward the right hand edge of the block member s fixedin the upper right hand corner thereof and by moving said blockmemberashereinbefore set forth the pointer of Vsaid screw maybe broughtto coincide'V with any one of' the horizontal lines of a block settingscale 18 which lines are numbered from one to twelve and disposed on theedge portion of the top 5 adjoining the recess 7. A pair of dummy scales19, one comprising numbers and the other comprising letters, may beplacedy on either side of said screw for the purpose of misleadingpersons engaged in malicious useof the device. c

A longitudinal check edge scale 2O is provided centrally of the devicetop 5 and com# prises a plurality of spaced lines extending horizontallyfrom the left hand edge'of said top across the recess and are numberedupwardly from zero to twelve at theirk right hand terminals. A guideVmember having a slotted arm 21 with a clamp screw 22 there; through andthrough the top 5is provided with a raisedstraight transverse end edgeportion 23 that may thus be brought to coincide with any one o thehorizontal lines of -said check edge scale. The block member 8,

when disposed withinits recess 7 projects above the top 5 of the cabinetand a slot 24 is provided in said member substantially flush with saidtop and extending under all the perforations 16 therethrough. YReferring to Fig. 2 wherein the straight edge 23 of the guide membercoincides with one of the horizontal lines of the check edge scale 20,the horizontal top'edge 25 of a check shown in .dotted lines is placedor inserted in the slot 24 and againstsaid straight edge and incoincidence with said horizontal line. An end check edge scale 26isprovided at the `lower right hand corner of the top 5 and comprises aplurality of spacedvertical lines each having a letter at its topalphabetically ranging from A on the left to P on the right. Thus theposition of the check is fixed by the horizontal line six of thel scaleY 2O and the line H of the scale 26 which coincideswith the right handend edge 27 of the check as clearly shown in Fig. 2 of the drawings. Thecheck is now in readiness to be punched which is done with a punch pin28, shownin detail Fig. 4, and which may besecured to the top 5 by means.of a chain 29. VA series `of slots depositor and that both the bank anddepositor are furnished with identical block members 8. Although thefigures, letters and the like may be shifted on said block members, Vitwillbe understoodthat the block member in possession ofthe bank mustalways be an Yabsolute duplicate with respect to said figures andletters of the block member held by the depositor and lsaid;duplicatesmay be designated by the letter A asshown at 31 on said block member inFig.I 2.' i Each depositor is furnished withl a combination or keynumber such as lA-8-(-y-H for the particular device shown herein. Thisnumber means that the depositors block member is designated by theletter A, the pointer screw 17 is to be set to the linev eight on theblock scale-18, the top edge 25 of the check is to be set to coincidewiththe horizontal line six of the check edge scale 20, and `that theright hand end edge 27 of said check is to be placed in coincidence withthe line H of the end edge yscale 26. It will thus be seen that theposition of the check is absolutely iXed bythe key numbers and it willalso be apparent thatfthe number of permutations made available `by thethree scales provides means whereby a 4suflicient number of combinationor key numbers may be provided for each and all the depositors of abank. Y

We will now assume that a check has been written by the depositor forseventy-nine thousand, five hundred, ifteen dollars and ninety-six cents($79,515.96). The depositor then places the check in the device as shownin thev drawings and in accordance with his hereinbefore describedcombination or key number and with the punch 28 he punches through theseven perforations 16 as collectively designated by the numeral 32 inFig. 3 beginning with the last number of cents at the right handvertical column of the block member 8 and moving to the left column bycolumn until thel first or highest figure of dol-` lars, namely seven,is reached. When this check is presented to the bank for payment thecashier, noting the name of the depositor thereon, will place the checkin his duplicate detector device beforecashing same. If the check hasnot been altered each of the perforations previously made by thedepositor will coincide vwith the perfo-Y rations 16l corresponding tothe amount of thev check, it being understood that the cashiers deviceis set in'accordance with the depositors combination or key number. Onthe other hand, if the check had been raised to seventy-nine thousand,seven hundred, fifteen dollars and ninety-six cents ($79,-

715.96) the cashier would note that the perforation seven in thehundredcolumn had not been punched or Was'not punched in the proper place andhe would immediately conclude that the check had been raised.

In order to providerfurther means whereby the readings of the scales maybe changed for the purpose of increasing their combination possibilitiesand also for the purpose of shifting the scale readings to deceive thosewho might have learned thereadings of a particular device, the lettersat the top of the end scale 26 may be placed on a slidable member 33 andan additional corresponding slidable member 34 with numbers thereon maalso be provided. The numbers at the rig t hand edge of the top scale 2Omay likewise be placed on a slidable bar 35, and all of said slidablemembers may be provided with screw or other means for shifting said`letters or numbers to other lines of the scales whereby their readingsmay be completely altered as Will be understood.

Having thus described my invention, it being understood that minorchanges may be resorted to in its construction and arrangement Withoutdeparting from the scope system of numbers andletters With a systeml ofperforations therefor, a scale on said top for setting the block member,said block member havin a slot intersecting all of its aforesaidpertorations and adapted to receive a check, a longitudinal check edgescale on said top extending transversely across said recess and blockmember for setting the top edge of the check, an end edge scale forsetting the end edge of the check, and a punch pin adapted to beinserted in the aforesaid perforations for punching holes through thecheck at the numbers on the block member to correspond with the amountfor Which the check is Written.

2. A check detector having in combination a top base member with arecess therein, a block member slidably disposed in said recess, saidblock member having a system of numbers and letters. with a system ofperforations therefor, a scale on said top for the setting of the blockmember, means for ad- 'ustably setting said block member, said lockmemberhaving a slot intersecting all of itsv aforesaid perforations andadapted tok receive a check, a longitudinal check edge scale on said topextending transversely across said recess and block member for settingthe top edge of the check, a slidable a punch pin adapted to be insertedin the aforesaid perforations for punching holes through the check atthe numbers on the block member to correspond With the amount charactersfor the lines of the tWo check edge scales.

In testimony whereof I affix my signature.
